Combustion chamber assembly with different curvatures for a combustion chamber wall and a combustion chamber shingle fixed thereto

A combustion chamber assembly group, comprising

• a combustion chamber for an engine that comprises at least one curved combustion chamber wall extending along two spatial directions, and
• at least one combustion chamber shingle that is affixed at an inner side of the combustion chamber wall and has a shingle edge that defines an outer contour of the combustion chamber shingle,
• wherein
• for an at least sectional abutment of the shingle edge at the combustion chamber wall at a minimum clamping force in an operational state of the engine, the combustion chamber shingle has a curvature at least at one section of the shingle edge that differs with respect to at least one of the spatial directions from a curvature of the combustion chamber wall with respect to this spatial direction, in a mounting state in which the combustion chamber shingle can be mounted at the combustion chamber wall.
